8.3.3 Limit value, hysteresis
Limit value alarm:
If this value is exceeded or not reached, this affects the
alarm relay output depending on the switching behav-
ior.
-200 to 0 to +850
Depends on setting range
min. and max.
Hysteresis limit value:
Difference between the switch-off and switch-on
threshold, e.g. for rising and falling temperatures.
0to2 to 100
8.3.4 Pre-alarm function
No function
Pre-alarm relay output is inactive
No function,
Absolute value,
Limit val. diff.
Absolute value:
Pre-alarm relay output is triggered if the value for the
pre-alarm is exceeded.
Limit val. diff.:
Here, the set value for the pre-alarm is used on a basis
that is relative to the limit value. If, for example, a pre-
alarm of 10 K is entered, the pre-alarm relay output
always switches at 10 K before the limit value, regard-
less of how the limit value is set.
V
Caution
The pre-alarm function is not part of the safety function!
8.3.5 Pre-alarm, hysteresis
Pre-alarm:
The value that triggers the pre-alarm relay output as an
absolute value or relative to the limit value.
-9999 to 0 to +9999
Pre-alarm hysteresis:
Difference between the switch-off and switch-on
threshold, e.g. for rising and falling temperatures.
0to2 to 100

Value range
(factory setting in bold)
H
The pre-alarm responds according to
its setting to the main measured val-
ue and also to the diagnostic func-
tions registered via the KD LED.
A pre-alarm is triggered according to
which measured value exceeds or
falls below the pre-alarm first.
